[SOLVED] NFS fails to mount during boot

Hi,

My NFS mount configured in /etc/fstab fails to mount during boot despite sudo mount -a working. For additional info I am using NetworkManager. I get the following errors by glancing at journalctl:

└─[01:17]-(^_^)-[$] sudo journalctl -b | grep nfs

In addition verifying systemctl mnt-steam yields the following:

My current fstab config:

# Steam Games NFS
192.168.70.148:/mnt/Steam/games   /mnt/steam-nfs   nfs   defaults,timeo=900,retrans=5,_netdev   0 0

The following config works but I would like to figure out why it fails during boot specifially;

servername:/home   /mountpoint/on/client  nfs  _netdev,noauto,x-systemd.automount,x-systemd.mount-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

.

I have also ensured to enable NetworkManager-wait-online.service as per Arch Wiki NFS documentation:

systemctl status NetworkManager-wait-online.service
● NetworkManager-wait-online.service - Network Manager Wait Online
     Loaded: loaded (/usr/lib/systemd/system/NetworkManager-wait-online.service; enabled; preset: disabled)

   Main PID: 709 (code=exited, status=0/SUCCESS)

Feb 19 01:16:44 arch-rig systemd[1]: Starting Network Manager Wait Online...
Feb 19 01:16:50 arch-rig systemd[1]: Finished Network Manager Wait Online.

Any help would be greatly appreciated as I don't know what to do to mitigate or have my NFS wait for my network to be ready as I do have _netdev option configured.

Re: [SOLVED] NFS fails to mount during boot

https://bbs.archlinux.org/viewtopic.php … 2#p2140602

NetworkManager-wait-online unfortunately does not at all mean that you've a functional network, it's set the moment the service started (and this is not better for any other network daemon, because otherwise they could stll the boot :rolleys: )

If you want to automount some network filesystem during boot, the (custom) mount service will have to ping-wait for the server to show up before establishing the mount, see eg. https://bbs.archlinux.org/viewtopic.php … 7#p2090547

Re: [SOLVED] NFS fails to mount during boot

Fixed with the following NFS options:

192.168.70.148:/mnt/Steam/games   /mnt/steam-nfs   nfs  _netdev,noauto,x-systemd.automount,x-systemd.mount-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0
